Brayden Marvin wants to be just like his dad when he grows up.Rick Marvin is a reserve deputy in Louisiana, and Brayden’s been helping him patrol the Mardi Gras parade near New Orleans for three years. "Since my dad does all the work, I thought that sometimes he would get tired, so I thought about being his backup," Brayden said. The eight-year-old even wears a Jefferson Parish Sheriff's Office uniform - complete with a radio, badge and handcuffs. Rick says his son takes his duties very seriously. "He has a very professional demeanor about himself," the reserve deputy said. "He has his child side and plays around, but he's on a different level." The desire to serve and protect runs in the family. Brayden’s grandfather served as an NOPD officer for 38 years. He has uncles who currently serve in the military and another is a state trooper. "Officers protect and serve and help other people when needed," Brayden said.
